Page 6: Introduction
This airflow pattern is known as laminar. Your LAF Series Hood is intended to be used as a work area that maximizes product quality control and minimizes risk of product exposure to contaminates. It should only be used with non-hazardous materials since the air being bathed over the product is reintroduced into the laboratory environment without being filtered again. -
Page 7: Installation
Assembly for detailed instructions. Once the LAF Series Hood is inside the laboratory, it should be positioned so that it is out of traffic patterns and away from room air currents that could disrupt its airflow. At least a foot of free space should be left on both sides of the unit for maintenance purposes. -
Page 8: Airflow
LAF Vertical Laminar Flow Hood User Manual Airflow The LAF Series Hood intakes air through a prefilter placed on the top of the hood. Five motor blowers push air through a HEPA filter and diffuser, causing uniform, laminar air to bath over the entire work surface. -
Page 9: Use Of The Laf Series Hood
Good Technique The operator is the critical factor in the successful performance of any LAF Series Hood. It is dangerous to rely on the unit to do all of the work. When properly maintained and operated, the LAF Series Hood will do an excellent job of controlling airborne contamination. -
Page 10: Operation
Since this LAF unit should only be used to work with non-hazardous materials, a “decontamination” procedure does not need to be completed before cleaning the inside of the hood. A “disinfectant” procedure should be completed to ensure the hood is sanitized before more compounding occurs. -
Page 11: Cautionary Notes
LAF Vertical Laminar Flow Hood User Manual Any spills that occur inside the hood should be cleaned immediately and the work surface should be disinfected before any more work occurs in the hood. Your facility should have a written plan available in case of a spill. Any wipes or mop pads used to clean the hood should be disposed in the same way as all other waste from the hood. -
Page 12: Maintenance
However, the prefilter should be changed at least once every 90 days. Replacement prefilters are available from Germfree and are usually a stock item. Call Germfree Customer Service to order. HEPA Filters The average life of a HEPA filter is 3 to 5 years or longer, depending on the cleanliness of the ambient air. -
Page 13: Filter Diffuser
LAF Vertical Laminar Flow Hood User Manual Filter Diffuser The HEPA filter is located behind the removable, perforated metal diffuser. Do not push items such as needles through the diffuser holes and do not hang items from any part of the diffuser. The diffuser should only be removed by your certifier and at that time it can be cleaned. -

This power is proportional to air speed. Alternatively, the velometer uses a probe that intakes air, and the force against the meter causes a deflection in the needle. If your facility does not have a certifier, Germfree can assist in finding one in your area. -
Page 16: Filter Housing Disassembly And Assembly
LAF Vertical Laminar Flow Hood User Manual Filter Housing Disassembly and Assembly Your hood is transported in two pieces and operational. Once the filter housing is placed on the frame, it can be plugged into an outlet and will be ready to be certified. Placing the filter housing on the stand requires at least four people to ensure the hood is not damaged during the process. -
